Encrypted data storage system based on key other-place storage and method

Abstract

The invention discloses an encrypted data storage system based on key other-place storage and method. The encrypted data storage system based on key other-place storage comprises a key control center,a key other-place storage system and a data encryption and decryption storage system, wherein the key other-place storage system comprises a first key control device, a key storage device and a firstquantum key distribution device; the data encryption and decryption storage system comprises a second key control device, a data encryption and decryption storage device and a second quantum key distribution device; the first quantum key distribution device and the second quantum key distribution device are in quantum communication connection; the first key control device is in communication connection with the key storage device and the first quantum key distribution device respectively; and the second key control device is in communication connection with the data encryption and decryptionstorage device and the second quantum key distribution device respectively. The key other-place storage system and the data encryption and decryption storage system can be separated at any distance safely and reliably, and other-place separate and safe storage between encryption and decryption keys and data can be realized.

Description

technical field [0001] The invention relates to the fields of information transmission and storage and information security, in particular to an encrypted data storage system and method based on key remote storage. Background technique [0002] Information is an important strategic resource for social development, and all levels from national security to personal privacy protection are all related to information security. Among them, under the impetus of digital technology, the conversion of information into data for storage and flow transmission are two crucial links in the process of information circulation and use. In these two links, information data is at risk of being eavesdropped and stolen. Therefore, how to protect information and data security is an eternally important topic. [0003] In the field of data storage, with the accumulation of current data volume and the substantial expansion of data applications, in addition to personal computers, servers and storage ...

AI Technical Summary

Problems solved by technology

[0006] The technical problem to be solved by the present invention is to provide an encrypted data storage system and method based on remote storage of keys for the above-mentioned deficiencies in the prior art. Unable to solve the problem of how to securely separate and store the encryption key and ciphertext data, the present invention can solve the problem of key security in the process of structured and unstructured data storage, database storage, data backup, cloud storage and cloud computing Storage and ciphertext data encryption and decryption storage problems, because the amount of encrypted keys can be many times smaller than the stored data, storing and managing the key store (key storage device) in different places is much less difficult than strictly managing data, so it can be effectively solved Security issues in the storage and computing process of various structured and unstructured data storage and databases, cloud storage and cloud computing
